These are side-by-side facts taken from each product guide: published specifications, strengths and caveats as their sources state them. This page is not a test, a ranking or a verdict about which model is better.

ecobee Smart Thermostat Essential (EB-STATE7-01)

Simple single-transformer systems with one stage of cooling, on a 2.4GHz network

ecobee's entry thermostat: a 2.8-inch touchscreen, temperature and humidity sensing only, and six wire terminals. The maker lists conventional 2H/1C or 1H/2C and heat pump 2H/1C, wired 24VAC through C and R. The Power Extender Kit and Trim Kit are sold separately, and Wi-Fi is 2.4GHz only.

Strengths

  • Hardwired 24VAC with no batteries, and it works with Alexa, Google Assistant and Apple HomeKit
  • Small 3.62-inch body with a full-colour touchscreen and the same ecobee app as the dearer models

Caveats

  • Six terminals only: no two-transformer wiring, no second cooling stage on a heat pump, no accessory terminal
  • Power Extender Kit and Trim Kit are both extra purchases, unlike every other ecobee model
  • 2.4GHz Wi-Fi only, no on-board speaker or occupancy sensor, and no bundled room sensor
